Recent work on intertemporal choice has varied the specification of every key aspect of modeling except the opportunity cost of consumption. We present evidence that consumers have present-biased perceptions of this parameter: they tend to underestimate the cost of short-term borrowing and the return to long-term saving. We develop a new theory that fits this evidence and is based on a more gen...

Step-flow growths of diamond on single-layer steps of hydrogenated diamond (001) surface have been investigated using the semiempirical molecular orbital method PM5. The chemical reactions at the first stage of growth have been calculated as a function of the charges biased to the substrates. When the frontier orbits of a pair of surface hydrogen atoms of step edge by negative charge 2 interact...

This paper presents a model which captures the technological spillovers created by foreign direct investment in Transition Economies. Skill-biased technological change is linked with endogenous labor supply which allows for unemployment. The technological spillover is divided into a neutral technological change and a skill-biased technological change. The first effect makes labor and capital mo...

A biased electrode is used in the Madison Symmetric Torus ~MST! reversed-field pinch @Fusion Technol. 19, 131 ~1991!# to manipulate plasma flow in order to study flow damping and momentum transport. Finite radial conductivity allows a radial current, which provides the toroidal torque that spins up the plasma. The applied torque is balanced by a viscous force that opposes toroidal flow accelera...

According to attribution theory stigmatized behaviors with biological explanations will be perceived more positively than those with psychological explanations, but informing people of the biological explanations of homosexuality has produced mixed results on attitudes. To examine if biased processing could explain previous findings we tested whether biased assimilation (initial attitudes’ effe...

On line analytical processing (OLAP) is an essential element of decisionsupport systems. OLAP tools provide insights and understanding needed for improved decision making. However, the answers to OLAP queries can be biased and lead to perplexing and incorrect insights. In this paper, we propose HypDB, a system to detect, explain, and to resolve bias in decision-support queries. We give a simple...

Evidence from both psychology and economics shows that people exaggerate the similarity between the information they have and the information available to others. I present a model of such information projection by assuming that after processing a signal a person overestimates the probability with which this signal is available to others. I apply the model to agency and communication settings. ...

Background and Purpose Dopamine agonists targeting D2 receptor have been used for decades in treating pituitary adenomas. There has little clear evidence implicating the canonical G protein signalling as mechanism by which suppresses growth of tumours. We hypothesize that ?-arrestin2-dependent is molecular dictating inhibitory effects on tumour growth. Experimental Approach The involvement ?-ar...

Thuiller et al. analyzed the consequences of anticipated climate change on plant, bird, and mammal phylogenetic diversity (PD) across Europe. They concluded that species loss will not be clade specific across the Tree of Life, and that there will not be an overall decline in PD across the whole of Europe. We applaud their attempt to integrate phylogenetic knowledge into scenarios of future exti...

When people retell events, they take different perspectives for different audiences and purposes. In four experiments, we examined the effects of this postevent reorganization of events on memory for the original events. In each experiment, participants read a story, wrote a biased letter about one of the story characters, and later remembered the original story. Participants' letters contained...
